Pleasant memories cover up long-forgotten family secrets in a thrilling new trailer for “Reversion.” The sci-fi film, directed by Jose Nestor Marquez, stars Aja Naomi King as Sophie, a young girl hung up on the past, and Colm Feore as her super-genius father.

The trailer begins with Sophie using the “Oubli,” a high-tech device that allows an individual to relive their happiest memories. For Sophie, this is the last time she saw her mother alive, 15 years ago. Sophie helps her father, the creator of the Oubli, sell the device to other vulnerable souls looking to relive their time with lost loved ones until one day, Sophie is kidnapped. Her assailant turns out to be a woman named Isa, who may know more about Sophie’s past than she does, and changes Sophie in ways she doesn’t entirely understand. As Sophie tries to deal with her assailants, the Oubli and her father, her precious memories of her mother begin to fade away into darker revelations.

“Reversion” opens on October 9 in New York, Los Angeles and Chicago, with additional releases to be announced.
